http://www.parts-express.com/precision-port-6-flared-port-tube-kit--268-354 buy two of these. One full length is 18", you can cut the second tube to add to the length you need for the tuning you are trying to achieve. These are much lighter then your current tube.

my last metering with the original Icons was 143.6db @ 10hz...... WITH FOUR 10"........ on a Crown A3000gti that set up was so flat the output only varied 3db from 10hz to 35hz.... the flattest response I have EVER seen with ported subs still KICKING myself in the ass for letting them go the only thing I would have changed on them would have been the surround... I was ripping them off the cone I would have went with a higher rolling surround and called it a day.... awesome woofer

Still to this day I have never heard anything as clean as this version of the Icon. In the right enclosure these things are like ear sex & get unbelievably loud! My last metering with two 15's on 3500 rms was a 150db @ 32hz!
